Each of the temple pieces or temples 46, 47 can include a first portion 51 that is pivotably coupled to the respective end portion 41, 42 of the front piece and any suitable second portion 52, such as curved or arcuate piece, for coupling to the ear of the user. In one embodiment the front piece 33 can be formed from a single piece of material, so as to have a unitary or integral construction. In one embodiment, such as illustrated in FIGS. 1 and 2 , the entire frame can be formed from a single piece of material so as to have a unitary or integral construction.

Glasses 31 can include a computing device, such as computer 61, which can be of any suitable type so as to be carried by the frame 32 and in one embodiment of a suitable size and shape so as to be at least partially disposed in one of the temples 46, 47 and in one embodiment, as illustrated in FIGS. 1 and 2 , the computer is sized and shaped similar to the size and shape of one of the temples 46, 47 and is thus disposed almost entirely if not entirely within the structure and confines of such temple 46, 47. In one embodiment, the computer 61 can be disposed in both of the temples. The computer 61 can include a central processing unit such as one or more micro processors (not shown), a suitable storage medium (not shown) such as a flash drive or memory that is electrically coupled to the central processing unit, and a suitable input device, a suitable output device or a combination of input and output devices that is electrically coupled to one or both of the central processing unit and the storage medium. The computer 61 additionally includes a battery 62 or other suitable portable power supply. In one embodiment, the battery 62 is disposed in one of the temples 46, 47, and in the glasses 31 shown in FIGS. 1 and 2 the battery 62 is shown as being disposed in left temple 46 and electrically coupled to the remainder of the computer 61 disposed in the right temple 47. The one or more input and output devices can include a connector or port (not shown) accessible from the outside of frame 32, a wireless receiver, transmitter or transceiver (not shown) or a combination of such devices.

Face wearable computing device or apparatus 31, which can be in the form-factor of glasses, can include one or more input sensors or peripheral devices for any suitable purpose including the collection of environmental and biometric contextual data and information used as input to the computer 61. Front piece 33 is provided with an outward-facing, forward-facing or front or outer surface 66 that faces forward or away from the user when the glasses 31 are mounted on the face of the user, and an opposite inward-facing, rearward-facing or rear or inner surface 67 that faces the face of the user when the glasses 31 are mounted on the face of the user. Such sensors can include inwardly-facing video sensors or digital imaging modules such as cameras 68 that can be mounted on or provided within the inner surface 67 of the front piece 33 or elsewhere on the frame 32 so as to be facing the user, and outwardly-facing video sensors or digital imaging modules such as cameras 69 that can be mounted on or provided with the outer surface 66 of the front piece 33 or elsewhere on the frame 32 so as to be facing away from the user. Such sensors, peripheral devices or peripherals can additionally include inward-facing digital sensors in the form of electro occulography sensors, or EOG sensors 71, and inwardly-facing sensors in the form of electroencephalogram sensors or EEG sensors 72. The EOG sensors 71 and EEG sensors 72 can each be mounted on or provided within the inner surface 67 of front frame piece 33 or elsewhere on the frame 32 so as to be facing the user. The outwardly-facing sensors can additionally include any suitable geometry sensor 73. Each of the peripherals or sensors are electrically coupled to the computer 61 by any suitable means such as a conductive lead, trace or cable 74, only a few of which are illustrated in the figures for simplicity. Additional peripheral devices or sensors for obtaining biometric inputs from the user can be provided and carried by or mounted on frame 32. Left and right optical elements 43, 44 can be additionally electrically coupled to the computer by any suitable means such as respective leads 74 when the optical elements include a display or other features that are controllable by the computer 61.

In one embodiment, illustrated in FIGS. 1 and 2 , first and second inwardly-facing cameras 68 can be provided, one near the bottom center of each frame holder 36 and first and second outwardly-facing cameras 69 are provided, one near the top center of each frame holder 36, 37. The inwardly-facing cameras 68 can be used for any suitable purposes including the extraction of biometric data using image analysis. Such biometric data can include image-based eye tracking, iris, facial or other recognition for example for identification purposes, facial expressions and the mood of the user. The outwardly-facing cameras 69 can be used for any suitable purpose, for example to capture respective images similar to those capturable by the left and right eyes of the user. First and second EEG sensors 72 can be provided on a portion of the frame that contacts the skin of the user, for example on the inner surface 67 or the bridge 38 or front piece 33. A plurality of EOG sensors 71 can be provided on the inner surface 67 around each of the left and right optical elements 43, 44 so as to be registrable with the left and right eyes of the user. In one embodiment, the EOG sensors 71 contact the skin of the user. The outwardly-facing geometry sensor 73 can be used for any suitable purpose, including the scanning and capturing of three dimensional geometry.

Computer 61 can additionally include an operating system that can include software used to access and control the peripheral devices connected to the computer, including but not limited to peripherals 68, 69, 71, 72 and 73. The computer can process the data from the multiple input sources or peripherals and can then optionally output data and information to the human sensory system through the use of the near ocular digital displays 43, 44 for consumption into the user's or wearer's eyes. For example, outwardly-facing digital sensors, peripherals or cameras 69 and geometry sensor 73 can be used to collect contextual data about the surroundings of the wearer, and sent to the computer 61 for processing as input data used by the computing systems operating within the computer. The inwardly-facing sensors, including sensors 78, 71 and 72, can be used to capture data from the wearer of the apparatus or glasses 31 such that this data can be sent to the computer 61 and the computing system of the computer can compute additional meaningful data from the input data sent from such sensors, which can further be utilized by the computing system to control various aspects of the computing system of the computer 61, including any software system of the computer 61, or aspects of the computing system or attached peripherals of the computer, such as visual outputs to optical displays 43, 44 or auditory outputs to speakers (not shown). For example, EEG sensors 72 can be used to measure the user's brain activity and state, for example voltage fluctuations within the neurons of the brain of the user, that can be sent to the computer 61 and used to control various functions within the software or operating system of the computer. An example is using EEG sensors 72 to mentally concentrate on a button on optical displays 43, 44 in order to click on it.

Such output data can additionally include audio signals that can delivered to speakers (not shown) mounted on or carried by the frame 32 or coupleable to the frame for mounting elsewhere for consumption into the wearer's ears. Other output methods such as haptics can be provided. Other outputs can include, for example, haptic capacitive touch surfaces on frames 32 of the glasses 31, haptic/tactile virtual objects for example via hand-worn accessories such as gloves or rings, world-tracked three-dimensional spatially rendered audio, electrochromic sunglasses, LEDs or other visual displays for notifications, and simulating acceleration and/or gravity via electrical stimulation of the user's inner ear. Additionally, the output from computer 61 can be sent to other local applications, other networked application that have access to some or all of the data acquired by the biometric sensors of glasses 31, or both.

As can be seen, the computer 61 can access and control connected sensors and peripherals, including without limitation peripherals 68, 69, 71, 72 and 73, which are electrically connected to the computer and send data to the computer over digital leads or cables 74. The computer and peripherals, and a suitable power supply such as battery 62, can be packaged and encased into a frame 32 that is designed as eyewear and can have the form factor of glasses. The glasses 31 can use optical displays 43, 44 together with biometric sensors to create a natural user experience where biometric thoughts and feelings and moods and concentration can control the user interface, provided for example by displays 43, 44.

In an additional possible use, optical displays 43, 44 can include electrochromic sunglasses. In this regard, software or electrical command from computer 61 causes the lenses 43, 44 to change their color, darkness or both. The computer 61 can additionally change other optical properties of the displays 43, 44, such as the focus distance of the scene as seen through the lenses.

The headwear of the present invention can be configured to re-display the world that the user is seeing not just as a stereo three-dimensional scene, but in one embodiment as a more realistic volumetric three-dimensional scene. In such a volumetric three-dimensional scene, the light displayed to the user is in focus at the proper focus distance. In one embodiment, the focus distance of the light passing through the optical display assembly or optical element assembly of the invention is controlled by software or otherwise by a local computing systems such as computer 61 or any other networked computer system. In one embodiment illustrated in FIG. 3 , headwear 78 includes a support structure 79, for example, frame 32 of glasses 31. An optical display or element assembly 80 of the headwear 78, such as left and right optical elements 43, 44 of glasses 31, can include a digital display matrix 81 and a plurality of optical layers or lenses disposed between the matrix 81 and the eye of the user that can be controlled by such software and/or computing system to adjust the focus distance of the light traveling through the assembly 30. Such optical layers can include any of the optimal layers or lens arrays disclosed herein. The display matrix can be of any suitable type, such as a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, any other light-emitting diode (LED) display or a laser display. In one embodiment, the plurality of optical layers or lenses includes a double concave lens 82 overlying the display matrix 81 and a double convex lens 83 overlying the double concave lens 82 so that the double concave lens 82 is disposed between the double convex lens 83 and the display matrix 81. In one embodiment, each of the lens 82, 83 has a cross-sectional area approximating the area of the display matrix 81. The display matrix 81 and lenses 32, 83 are each carried by the frame or support structure 79 of the headwear 78, such as frame 32 or glasses 81. Each of the lenses can be movable is directions towards and away from the display matrix 81, and suitable linear movement devices such as linear actuators (not shown) can be carried by the support structure 79 for providing such respective lineal movement. In one embodiment (not shown), only one of lenses 82, 83 is provided and such lens is movable towards and away from the display matrix 81 by its linear actuator. In the foregoing manner, one or both of lenses 82, 83 serve as software or computing system focusable lens. It is appreciated that other software or computer focusable lens can be provided and be within the scope of the invention. For example, a liquid crystal with a tunable refractive index, or one or more deformable liquid or fluid-filled lenses, can be utilized instead of lenses 82, 83 and serve as the software or computer focusable lens of the invention.

The display matrix 81 and linear actuators are electrically coupled to a suitable miniaturized computer system or computer 86, such as computer 61 of glasses, also carried by the support structure 79. Each such optical element assembly 80, which can serve for example as one or both of optical elements 43 and 44 of glasses 31, can as described above include display matrix 81, double concave lens 82 and double convex lens 83 as well as an outwardly-facing digital sensor or image display module 87, such as camera 69 of glasses 31, and one or more inwardly-facing digital sensors in the form of camera 88, which can be similar to inwardly-facing cameras 68 of glasses 31. The optical element assemblies 80 of the headwear 78 can each be carried by the support structure 79 and electrically coupled to computer 86.

In operation, the one or more cameras 88 and/or other inwardly-facing sensors capture the scene in real-time and feed the data into the miniaturized computer 86. The computer then runs an operating system, alone or in combination with local application and/or networked applications that have access to some or all of the sensor data from cameras 88, and produces output that is sent to the display matrix 81. If no application is running, the default behavior is to pass the data from the sensors 88 through to the computer 86, as well as apply necessary camera transformations and other software procedures, to make the user see the unmodified view as if the user was not wearing the headwear 78.

Once one or more of the local application, the networked application and the computer 61 produce output data, such data is sent to the display matrix 81, which converts the data into visible photons on the matrix 81. Next, those visible photons pass through one or more of the optical lenses 81, 82 which enhance the realism of the displayed representation of reality by for example adjusting the optical focal distance between the eye and the image viewed on the matrix 81. As an example, the combination of convex lensing element 82, concave lensing element 83, and a software or computer algorithm provided in one or more of computer 86, the local applications or the networked applications, which algorithm is informed by both knowledge of the scene and by knowledge of the view point at which the user is looking, can be used to adjust the optical focus distance between the display matrix 81 and the eye of the viewer of the viewed scene, as shown schematically in FIG. 3 . An optical path 89 of a photon, from one of the pixels on display matrix 81, is shown in FIG. 3 , and includes a first path segment 89 a from the display matrix 81 to one surface of convex lens 82, a second path segment 89 b from the opposite surface of convex lens 82 to one surface of concave lens 83 and a third path segment 89 c from the opposite surface of concave lens 83 to the eye of the user. Adjusting the scene's focus distance can achieve several goals, including focusing individual objects to be at their correct optical distances, so as to achieve a level of realism called volumetric three dimensional graphics which is a better than standard stereo three dimensional graphics. Such adjustment of the scene's focus distance can also render objects at slightly different distances by using a software implementation of the user's optometry prescription. For example, if the user's prescription is minus 0.5 diopters in the left eye and minus 0.25 diopters in the right eye, then the objects shown to the left eye can just be drawn 0.5 diopters closer to the eye of the viewer than reality, and the objects shown to the right eye drawn 0.25 diopters closer to the eye of the viewer than reality, which achieve the optometry prescription without requiring any prescription lenses but instead an adjustment of the input data provided to the software algorithm.

It is appreciated that in one embodiment none of the lenses in optical display assembly 80 is movable, whether the assembly 80 include both lenses 82, 83 or only one of such lenses 83, 83.

One embodiment of determining the three dimensional point that the user is focusing on and/or the distance from the user's eyes to the three dimensional point that the user is focusing on, sometimes referred to herein as Z distance, for the purpose of driving a focusable display, and/or as inputs into a computer system, is illustrated in FIG. 4 . An eye-tracking sensor, such as one or more cameras 68 on right optical element holder 37 of glasses 31 or the camera 88 of headwear 78 pertaining to the right eye of the user, determines the gaze vector 96 of the right eye of the user, that is the angle and direction at which the right eye of the user is pointed or gazing at a point in time, for example when viewing an object or virtual position in space. Another or the same eye-tracking sensor, such as one or more of cameras 68 on left optical element holder 36 of glasses 31 or the camera 88 of head wear 78 pertaining to the left eye of the user, simultaneously determines the gaze vector 97 of the left eye of the user, that is the angle and direction at which the left eye of the user is pointing or gazing at the point in time, for example when viewing the object or virtual position in space being viewed by the right eye at the time of measurement. The gaze vectors 96, 97 converge so as to intersect at such object or virtual position in space. Any suitable sensing system that can include the left eye-tracking sensor and/or the right eye-tracking sensor and/or additional eye tracking sensors tracks properties of the user's right and left eyes, for example the two pupils, irises, and/or eye muscles of the eyes, to determine the user's inter-ocular distance 98, mood, intent, or other biometric properties that can be computed and derived within a computer system, such as computer 61 of glasses 31, computer 86 of head wear 78, or other local or networked computers communicating with such computers 61 or 86. The inter-ocular distance is the distance between the eyes of the user, as shown in FIG. 4 .

A computing system, such as computer 61 of glasses 31, computer 86 of headwear 78, or other local or networked computers communicating with such computers 61 or 86, uses inputs 96-98, and/or other inputs potentially including digital sensor data obtained from the headwear or elsewhere, waveforms, images and/or geometry of the scene that the user is looking at, to produce outputs including a three-dimensional point or gaze point 101 in space that the user is looking at and/or a Z distance 102, expressed in linear distance or dioptric/optical distance or both, from the user's eyes to the gaze point 101. The right gaze vector 96 intersects the left gaze vector 97 at such gaze point 101. The three-dimensional point 101 can be used as an input to a computer software system, for example computer 61 of glasses 31, computer 86 of headwear 78, or other local or networked computers communicating with such computers 61 or 86, to map a virtual position in three dimensional space where the user is looking in order for the user to control aspects of such software system. The Z distance 102, which can be expressed as dioptric distance where the dioptric distance equals one divided by the linear distance, is useful as an input to a computing and display system of the present invention that renders visible photons that are in focus at the proper optical focus distance that the user is looking at. More detail regarding the foregoing is disclosed in a paper entitled Volumetric World Display dated May 15, 2012 authored by Jon Rodriquez, the entire content of which is incorporated herein by this reference.

FIG. 5 illustrates a user viewing an immersive, computer-generated scene that looks just as realistic as the real-world by use of one embodiment of the headwear of the present invention. Although not illustrated in FIG. 5 for simplicity, the headwear 111 of FIG. 5 can be in the form of glasses, goggles, eyewear or any of the other headwear discussed above, and can include any suitable support structure (not shown), such as a frame, for supporting the components of the headwear on the head of the user. Headwear 111 can include any suitable left and right optical elements or assemblies 113, including any of the optical elements discussed above, mounted on or secured to the support structure. In one embodiment, each of the left and right optical elements or assemblies 113 are in the form of any suitable light field array such as a suitable plenoptic lens system. In one embodiment, each assembly 113 includes a high density digital display or matrix 114, for example any of the displays discussed above with respect to display matrix 81, having a display surface 116. A lens array 117, which can be of micro scale or nano scale, overlies the display matrix 114 and is included in the assembly 113.

In one embodiment, the lens array 117 includes a plurality of micro-scale lenses 118 arranged in an array that can be substantially centered on an eye of the user. Although the lens array 117 can be flat or have any other suitable configuration or shape, in one embodiment the lens array has suitable transverse dimensions so as to encompass the entire peripheral vision of the user. In one embodiment, the lenses 118 are arranged in an arcuate array 117 that can be substantially centered on an eye of the user so, for example, to warp around the eye of the user, and in one embodiment such arc has substantially the same curvature of the eye and has sufficient arcuate dimensions to encompass the entire peripheral vision of the user. In one embodiment, the curvature of the arcuate array is a radial curve. Each of the micro lenses can be made from any suitable material such as plastic, glass or another suitable transparent material, and can have an outer surface 122 that faces the eye of the user during use that can be either flat, concave or convex and is shown in FIG. 5 as being concave.

The lens array 117 can be carried by or mounted on any suitable member or element, and in one embodiment is mounted on a suitable support element 119 made from any suitable transparent materials such as glass or plastic. The support element includes an arcuate surface 120 on which the lenses 118 are mounted or secured and which defines the arcuate shape and dimensions of the arcuate array 117. Although in the illustrated embodiment the lenses 118 are fixed or non-movable, it is appreciated that lenses 118 can be movably carried by the support element 119 and be within the scope of the invention. In this regard, for example, the support element 119 can include can include nano materials and/or nano particles that are movable or actuatable for example by magnetic or electric fields to cause the lenses 118 to move on the arcuate surface 120 of the support element 119.

Each assembly 113 can further include a suitable focusing element 121 for eliminating artifacts such as chromatic aberrations from the light passing through the assembly. In one embodiment, the focusing element 121 is disposed between the display matrix 114 and the support element 119 of the lens stray 117.

A plurality of optical paths 131-135 are shown in FIG. 5 and illustrate the travel of respective photons emitted from the display matrix 114 and include a first path segment 131 a-135 a from the display surface 116 of the matrix 114 to the rear of the support element 119, a second path segment 131 b-135 b from the rear of the support element 119 to the rear surface of a micro lens 118, and a third path segment 131 c-135 c from the outer surface 122 of the micro lens 118 to the eye of the user. The exploded portion of FIG. 5 shows a subarray 141 of a plurality of pixels 142 of display matrix 114, and a plurality of optical paths 143, 144 of photons emitted from a couple of such pixels 142 and having first path lengths 143 a, 143 b from the display surface 116 of the subarray 141 to the rear surface of the micro lens 118 and respective second path lengths 143 b, 144 b from the outer concave surface 122 of the micro lens 118. As can be seen from FIG. 5 , the concave outer surface 122 of each micro lenses 118 causes the optical paths of photons emitted from the pixels 142 of the subarray 141 operated on by such lens 118 to diverge from each other as they are emitted from the outer surface 122 of the lens 118. A convex surface on the micro lenses 118 would cause the optical paths of such a subarray 141 to converge from the outer surface 122 of the lens 118.

In one operation of such embodiment, data or signals from a miniaturized computer running an operating system, for example computer 61 or computer 86, and/or local application(s) and/or networked application(s), is sent to display matrix 81, which produces photons based on the input data or signal. The optical assembly 113, which in one embodiment includes display matrix 81, focusing element 121 and the plurality of micro leases 118, not only can display software controlled color and intensity like a normal pixel, it can also send different color and intensity of light in different directions, for example in the manner discussed above. The array 117 of these superpixels 118 can thus render an optical four dimensional light field, which is sufficient to reproduce the complete visual appearance of the real world, including optical focus and multi-focus, that is having different objects be at different distances in a single frame. When the micro lenses 118 are movable, the steering of light in different directions can also be assisted by other micro- and macro-scale optics layers (not shown), including optics that mechanically move or deform in response to electromagnetic fields. Such optic layers can also used to direct the light, including optical paths 131-135 and 143-144, so that it impinges upon the user's eye from all directions, for example in a wide-angle configuration, immersing the user in the virtual world.

FIG. 6 illustrates one embodiment of a user in an immersive, computer-generated scene that looks just as realistic as the real-world. Headwear 151 therein is similar to headwear 111 and would be used with a miniaturized computer running an operating system, for example computer 61 or computer 86, and/or local application(s) and/or networked application(s). Although not illustrated in FIG. 6 for simplicity, the headwear 151 can be in the form of glasses, goggles, eyewear or any of the other headwear discussed above, and can include any suitable support structure (not shown), such as a frame, for supporting the components of the headwear on the head of the user. Headwear 151 can include any suitable left and right optical elements or assemblies 153, including any of the optical elements discussed above, mounted on or secured to the support structure. In one embodiment, each of the left and right optical elements or assemblies 153 are in the form of any suitable light field array such as a suitable plenoptic lens system. In one embodiment, each assembly 153 includes a high density digital display or matrix 154, for example any of the displays discussed above with respect to display matrix 81, having a display surface 156. A lens array 157, which can be of micro scale or nano scale, overlies the display matrix 156 and is included in the assembly 153.

In one embodiment, the lens array 157 includes a plurality of micro-scale lenses 158 arranged in an array that can be substantially centered on an eye of the user. Although the lens array 157 can be arcuate or have any other suitable configuration or shape, in one embodiment the lens array has suitable transverse dimensions so as to encompass the entire peripheral vision of the user. In one embodiment, the lenses 158 are arranged in a flat array 157 that can be substantially centered on an eye of the user and has sufficient dimensions to encompass the entire peripheral vision of the user. Headwear 151 is configured so that the assembly 153 is located very close to the eye of the user, and thus has a very near ocular distance, when in use. Each of the micro lenses can be made from any suitable material such as plastic, glass or another suitable transparent material, and can have an outer surface 162 that faces the eye of the user during, use that can be either flat, concave or convex and is shown in FIG. 6 as being concave.

The lens array 157 can be carried by or mounted on any suitable member or element, and in one embodiment is mounted on a suitable support element 166 made from any suitable transparent materials such as glass or plastic. The support element 166 includes a flat surface on which the lenses 158 overlie. Although in the illustrated embodiment the lenses 158 are movable, it is appreciated that lenses 158 can be fixably carried by the support element 166 and be within the scope of the invention.

In one embodiment, the lenses 158 are movable relative to the support element 166. Although the assembly 153 can include any suitable means tor moving the lenses 158 individually or in unison relative to the support element 166, in one embodiment each lens 158 is mounted on a first electromagnet 167 which overlies and is movable relative to a second electromagnet 168. The electromagnets 167 and 168 can each be of nano or micro scale size and can extend parallel to but spaced apart from each other. The first electromagnet can move in directions, including first and second orthogonal directions in its plane and thus parallel to the second electromagnet 168, and in one embodiment can additional move towards and away from the second electromagnet 168 regard. Any suitable means can be provided for causing such movements, and in one embodiment a magnetic particle fluid, for example nano materials and/or nano particles (not shown), is disposed between the first and second electromagnets 167, 168 and a magnetic field or flux generator or other suitable means can be provided for causing the first electromagnet 167 to move in the desired direction(s) relative to the second electromagnet 168. In one embodiment, electrostatics are utilized to cause such movement.

Each assembly 153 can further include an optional optical layer 171, which in one embodiment can be highly refractive, disposed between display matrix 154 and the support element 166.

Headwear 151 includes at least one eye-tracking sensor, and ideally at least one per eye, tracking one or both eyes of the user using the headwear. In one embodiment, the eye-tracking sensor(s) can each be in the form of an inwardly-facing digital sensor or camera 172, which can be similar to inwardly-facing cameras 68 of glasses 31.

The exploded portion of FIG. 6 includes a plurality of RGB matrices 173 provided, for example, on the display surface 156 of the display matrix 154. Each of the three pixels of each matrix is capable of emitting a separate photon. In FIG. 7 , the first and second electromagnets 167, 168 are shown in three relative positions with respect to each other. Additionally in FIG. 7 , a plurality of optical paths 176-178 are shown and illustrate the travel of respective photons emitted from the respective RGB matrix 173 and include a first path segment 176 a-178 a from the matrix 173 to the rear of the micro lens 158, and a second path segment 176 b-178 b from the outer surface 162 of the micro lens 158 to the eye of the user. As can be seen from FIG. 7 , the concave outer surface 162 of each micro lenses 158 causes the second path segments 176 b-178 b of photons emitted from the matrix 173 to continue in a direction parallel to the first path segments 176 a-178 a when the first electromagnet 167 is aligned, registered or concentrically disposed with respect to the second electromagnet 168. When viewed in a plane as in FIGS. 6 and 7 , the second path segments 176 b-178 b of photons emitted from the matrix 173 are redirected to an inclined first direction relative to or with respect to the first path segments 176 a-178 a when the first electromagnet 167 is offset in a first direction relative to the second electromagnet 168 and are redirected to an inclined second direction relative to or with respect to the first path segments 176 a-178 a when the first electromagnet 167 is offset in a second direction, that is opposite to the first direction, relative to the second electromagnet 168. A convex surface on the micro lenses 158 would cause the optical paths to similarly redirect when the first electromagnet 167 is moved to an offset position relative to the second electromagnet 168.

In operation, the scene can rendered through a combination of several means. Light color and intensity data travels to the display matrix 154, which emits visible photons. Simultaneously, electromagnetic commands controlled by the computer system are sent to the lens array 157 of mechanically actuated micro lenses 158 whose movement and/or deformation is actuated by the interaction of such electromagnetic commands with the first and second electromagnets 167 and 168. The effect of this movement and/or deformation of the micro lenses 158 and/or their housings and/or a liquid is to steer the light from the display matrix 154, 173 in software-controlled directions 176 b-178 b, resulting in the visible photons emitted by the matrices having not just software-controlled color, intensity, and (x,y) coordinates, but also software controlled left-right and up-down direction of emission. In one embodiment, such commands can be encoded as electromagnetic or acoustic waveforms. When such an array 157 is tiled across a vast array, such as display matrix 154, and/or built into or with an optical layer containing or adjacent to such array, the resulting total system has the power to render a so-called “four dimensional light field”, meaning that the system takes in data specified with (x,y,pan,tilt) spatial coordinates, or coordinates in one of several other equivalent parameterizations of four dimensional light fields. The resulting “four dimensional light field display” or “four dimensional plenoptic display” is able to render multiple objects that are in focus at a variety of different focal distances—in other words, a scene with all the optical realism of physical reality.

The inclusion of the eye trackers 172 is useful for stabilizing the displayed scene relative to the rotation of the user's eyeball, became the optical center of the eyeball is not in the same place as the rotational center of the eyeball, such stabilization is beneficial. Such eye tracking is also useful as an input to a software or other operating system of the computer (not shown) of headwear 151 and/or local application(s) and/or networked application(s) communicating with such computer, for example in an interface where the user looks at an object to seamlessly and effortlessly interact with the object.

In addition, the input from eye tracker or inwarding facing sensor or camera 172 can be used for a display technique called “saccade amplification”, which increases the user's field of view by “moving the world” when the user moves their eyes. For example, if the user looks left by ten degrees, the world can move right by ten degrees, resulting in a total movement of 20 degrees for a 2× amplification of how many degrees the user can turn their view. This could also give the user the ability to extend their peripheral far beyond the normal human field of view, for example, to include views behind the person's head. This saccade amplification technique, combined with viewing data from cameras, for example any suitable outward-facing camera included in the headwear 151, that see to the left and right of the user's head as well as forward, results in expanded peripheral vision and awareness for the user, a great boon for drivers and pilots who need to be aware of their surroundings in all directions.

A system and methods for interactive local and remote display and control of a computer controlled via signals and with output to a light based output system can be provided. In one embodiment, illustrated in FIG. 8 , headwear 191 can be in the form of glasses, goggles, eyewear or any of the other headwear discussed above, and can include any suitable support structure (not shown), such as a frame, for supporting the components of the headwear on the head of the user. Headwear 191 can include any suitable left and right optical elements or assemblies 192, which can be similar to any of the optical elements or assemblies discussed herein including optical elements 43, 44 of glasses 31, display assembly 80 of headwear 78, optical assembly 113 of headwear 111 or optical assembly 153 of headwear 151. In one embodiment, the optical assembly 192 includes any suitable display matrix 193, which can be similar to display matrix 81 discussed above, and any suitable optical layer 194, which can be similar to any of the optical, layers herein including optical layers 82, 83, lens array 117 or lens array 157.

Headwear 191 can include any suitable computing system, including any of the computers disclosed herein such as computers 61 and 86. In one embodiment, a micro computer system or computer 201 powered by a suitable rechargeable battery 202, which can be similar to battery 62, is provided. Computer 201 can receive a data stream from one or more image sensors 203, which can be of any suitable type such as camera 69, geometry sensor 73 or as combination thereof, positioned such that the image sensor 202 senses the same scene as a human eye. One or more additional image sensors 206, which can be of any suitable type such as similar to camera 68, EOG sensor 71 or a combination of the foregoing, is positioned such that a human eye and surrounding region is visible in the field of view of the sensor. Sensor 206 delivers a data stream to the micro computer system 201 as well. One or more additional sensors 207, which can be of any suitable type such as EOG sensors 71, EEG sensors 72 or any other sensor for obtaining biometric information from the user, can also be connected to the micro computer 201. Additionally, the micro computer system or computer 201 is connected to a means of data transmission 211 to one or more networked computers, which in one embodiment can include first networked computer 212, second networked computer 213 and third networked computer 214, such a way that data cart be simultaneously transmitted to and from the micro computer 201 by one or more of such networked computers. The data transmission means can be of any suitable form, including wired, a local area network, a wide area network, a dynamic area network, cellular transmission, peer to peer or a combination of any of the foregoing. Each of computers 212-214 can be of any suitable type, and each include at least a central processing unit 216 and one or more storage mediums 217.

The micro computer system 201 connects to a digital display assembly 192. The digital display system or assembly 192 is positioned such that light emitted from display matrix 193 passes through one or more layers 194 of material that may modify the path of the light such that the light is delivered to a human eye.

In one method of operation, the micro computer system 201 receives inputs from one or more of sensors 203, 206, 207 and executes procedures in response to the inputs. In one example, a procedure processes the input from the digital sensor system 206 to determine properties of the human eye that it senses. The procedure then modifies the signals delivered to the display matrix 193 in response to the measured properties. In another example, the input stream from the outward facing sensor system 203 is processed and output to the display matrix 193. In another example, a procedure receives data from the outward facing sensor system 203 and delivers it along the means of networked communication 211 to a networked computer in the first networked computer 212, which in one embodiment can be a grid computer, a computing cluster or a remote cloud computer. The first networked computer 212 stores the sensed data in its digital storage medium 217 and then a collection of software or other instructions running on one or more second networked computers 213 executes procedures on the data to extract information. The procedures on the second networked computers 213 can include reality as a platform software. The extracted information is then delivered back along the network 211 to the micro computer system 201 and a procedure running on the micro computer system 201 executes a procedure to output the information to the display matrix 193.

The foregoing procedures may be modified in response to other procedures or signals received from inputs to the micro computer system 201, including inputs from any of sensors 203, 206, 207. In one example, a third-party application on the third networked computer 214 sends a command to the second networked computers in 213 which in turn delivers a signal to the micro computer 201 which modifies the procedures embedded in computer 201.

In another embodiment of the headwear of the present invention, illustrated in FIG. 9 , headwear 231 can be provided in any suitable form such as glasses, goggles, eyewear or any of the other headwear discussed above, and can include any suitable support structure (not shown), such as a frame, for supporting the components of the headwear on the head of the user. Headwear 231 can include any suitable left and right optical elements or assemblies 232, which can be similar to any of the optical elements or assemblies discussed herein including optical elements 43, 44 of glasses 31, display assembly 80 of headwear 78, optical assembly 113 of headwear 111, optical assembly 153 of headwear 151 or optical assembly 192 of headwear 191. In one embodiment, the optical assembly 232 includes any suitable display matrix 233, which can be similar to display matrix 81 discussed above, and any suitable optical layer or layers 234, which can be similar to any of the optical layers herein including optical layers 82, 83, lens array 117 or lens array 157 and can further include prisms and/or mirrors and/or waveguides and/or other optics. The optical layer 234 can include hemispherical optics of any suitable size and configuration, include hemispherical optics similar to micro lenses 118 or 158 that are provided in an array overlying the display matrix or a larger hemispherical element such as a single hemispherical element 236 that covers the entire or substantially all of the display matrix 233.

The hemispherical element 236 can be made from any suitable material such as plastic, glass or another suitable transparent material, and can have an outer surface 237 that faces the eye of the user during use that can be either flat, concave or convex and is shown in FIG. 9 as being concave.

Each assembly 233 can further optionally include a suitable focusing element 238 for eliminating artifacts such as chromatic aberrations from the light passing through the assembly. In one embodiment, the focusing element 238 is disposed between the display matrix 233 and the hemispherical element 236.

A plurality of optical paths 241-244 are shown in FIG. 9 and illustrate the travel of respective photons emitted from the display matrix 233 and include a first path segment 241 a-244 a from the surface of the display matrix 233 to the rest of the focusing element 238, a second path segment 241 b-244 b through the focusing element and a third path segment 241 c-244 c from the outer surface 237 of the hemispherical element 236 to the eye of the user. As can be seen from FIG. 9 , the concave outer surface 237 of the hemispherical element 236 causes the optical paths of photons emitted from the display matrix 233 and operated on by the element 236 to diverge from each other as they are emitted from the outer surface 237 of the hemispherical element 236. A convex surface on the hemispherical element 236 would cause the optical paths emitted from the display matrix 233 to converge from the outer surface 237 of the hemispherical element 236.

Headwear 231 can include any suitable computing system, including any of the computers disclosed herein such as computers 61 and 86 and/or any combination of one or more other local or networked computers. In one embodiment, a micro computer system or computer 251 powered by a suitable rechargeable battery (not shown), which can be similar to battery 62, is provided. Computer 251 can receive a data stream from one or more image sensors 256, which can be of any suitable type such as camera 69, geometry sensor 73 or a combination thereof, positioned such that the image sensor 256 senses the same scene as a human eye. One or more additional image sensors 257, which can be of any suitable type such as similar to camera 68, EOG sensor 71 or a combination of the foregoing, is positioned such that a human eye and surrounding region is visible in the field of view of the sensor. Sensor 257 delivers a data stream to the micro computer system 251 as well. One or more additional sensors (not shown), which can be of any suitable type such as EGG sensors 71, EEG sensors 72 or any other sensor for obtaining biometric information from the user, can also be connected to the micro computer 251. The micro computer system or computer 251 connects to digital display matrix 233. The digital display system or assembly 232 is positioned such that light emitted from display matrix 233 passes through one or more layers of material, which can include hemispherical element 236, that may modify the path of the light such that the light is delivered to a human eye.

In one method of operation, the headwear or system 231 captures data of the scene in front of the user, using digital sensor or camera 256. Then, the miniaturized computer system 251 executes computer software or embedded operations that perform intelligent analysis and/or modifies, enhances, or reproduces the data stream in various ways. Then the miniaturized computer 251 outputs the new data or signals and sends it to display matrix 233. The display matrix produces visible photons, that travel along optical paths 241-244 and are sent through lenses and/or prisms and/or mirrors and/or waveguides and/or other optics 236 that redirect visible photons to the user's eyes.

In one embodiment of this system or headwear 231 designed for stereo 3D, there can be just one miniaturized computer 251, but two each of the components including camera 256, optical assemblies 232 and sensor or camera 257 such that there are one of each of such components for each eye. This stereo formulation produces a stereo 3D experience where data is displayed to each eye and combine to form a 3D display system. The same miniaturized computer 251 can be used to process both eyes' data streams.

In another embodiment of the headwear of the present invention, illustrated in FIG. 10 , any suitable form of headwear can be provided, including classes, goggles, eyewear or any of the other headwear discussed above, and in one embodiment is in the form of a pair of glasses 261. The glasses can be of any suitable type, including glasses 31, and like reference numerals have been used to describe like components of glasses 261 and 31. For simplicity, on a portion of the glasses 261 are shown in FIG. 10 . Headwear or glasses 261 can optionally include left and right optical lenses 262, 263 secured within respective left and right optical element holders 36, 37. The glasses 261 can additionally include any suitable left and right optical elements or assemblies 266, which can be similar to any of the optical elements or assemblies discussed herein including optical elements 43, 44 of glasses 31, display assembly 80 of headwear 78, optical assembly 113 of headwear 111, optical assembly 153 of headwear 151, optical assembly 192 of headwear 191 or optical assembly 232 of head wear 231. Although only one optical assembly 266 is shown in FIG. 10 , it is appreciated that an optical assembly 266 can be provided for both eyes of the user.

In one embodiment, the optical assembly 266 includes any suitable display matrix 267, which can be similar to display matrix 81 discussed above, and any suitable optical layer or layers 268, which can be similar to any of the optical layers herein including optical layers 82, 83, lens array 117 or lens array 157 and can further include prisms and/or mirrors and/or waveguides and/or other optics. In one embodiment, illustrated in FIG. 10 , the optical layer is a prism 268 having a suitable size and configuration and including a first surface 271 for receiving light from display matrix 267 and a second surface 272 for emitting light to the eye of the user. The prism 268 extends over all or at least a portion of the optical element holder 36, 37 so to permit the user to see the second surface 272 of the prism when the eye of the user is viewing through the optical element holder. The first surface 271 faces upwardly from the frame 32 and the display matrix 267 overlies the prism so that photons and light emitted by the display matrix 267 impinge the first surface 271. The prism is sized and shaped so that the light is refracted within the prism and is directed towards the eye of the user he the second surface 272. In this regard, the second surface 272 can be convex so as to direct the light towards the center of the eye. The prism can optionally be sized and shaped so as to magnify the image projected by the display matrix 267 and the light travels through the prism, so that the image viewed from the second surface 272 is larger in one or more dimensions than the image emitted from the display matrix 267.

Headwear or glasses 261 can include any suitable computing system, including any of the computers disclosed herein such as computers 61 and 86 and/or any combination of one or more other local or networked computers. In one embodiment, a micro computer system or computer 276 powered by a suitable rechargeable battery (not shown), which can be similar to battery 62, is provided. Computer 276 can receive a data stream from one or more image sensors 277, which can be of any suitable type such as camera 69, geometry sensor 73 or a combination thereof, positioned such that the image sensor 277 senses the same scene as a human eye. One or more additional image sensors can be provided, including any of the other biometric or other sensors disclosed herein. In one embodiment, an outwardly-facing geometry sensor 278 can be used for any suitable purpose, including the scanning and capturing of three dimensional geometry. The micro computer system or computer 276 connects to digital display matrix 267.

Headwear or glasses 261 overlays information from computer 276, over the real scene, into the user's eyes. The system augments reality and/or overlays information and/or composites virtual objects into the scene.

In one method of operation of glasses 261, the input data from the one or more sensors, including sensor 277, is rendered by miniaturized computer 276 that decides what data to show based on the operating system and/or local application(s) and/or networked application(s) that are running combined with contextual awareness using digital sensors 277, 278. The system can be a display for one eye only, or for two eyes.

As discussed and seen in FIG. 10 , the system or glasses 261 has a display matrix 267 that is not directly in front of the user's eye, and lenses and/or prism and/or mirrors and/or waveguides and/or other optics 268 to redirect the displayed photons into the user's eye in such a way that the photons overlay with the real-life scene. In one embodiment, the lenses and/or prisms and/or mirrors: and/or waveguides and/or other optics 268 show the data privately, so that the user's eye can see the graphics, but a third party looking at the user only sees the user's face and eye, but not the data.

In another embodiment of the headwear of the present invention, illustrated in FIG. 11 , any suitable form of headwear can be provided, including glasses, goggles, eyewear or any of the other headwear discussed above, and in one embodiment is in the form of a pair of glasses 291. The glasses can be of any suitable type, including glasses 31, and like reference numerals have been used to describe like components of glasses 291 and 31. For simplicity, on a portion of the glasses 291 are shown in FIG. 11 . Headwear or glasses 291 can optionally include an optical lenses 292 secured within each of the left and right optical element holders 36, 37. The lens 292 has a front surface 293 and an opposite rear surface 294. The left and right ends 41,42 of the frame front piece 33 can optimally include respective left and right extensions 296, 297 that extend rearwardly from the respective ends 41, 42. Left and right temples 46, 47 are provided, and can either be fixedly secured to respective extensions 296, 297 or removably attachable to the respective extensions. In one embodiment, any suitable connector mechanism 298 is provided for securing the temple to the respective frame extension.

Headwear or glasses 291 can include any suitable, computing system, including any of the computers disclosed herein such as computers 61 and 86 and/or any combination of one or more other local or networked computers. In one embodiment, a micro computer system or computer 301 powered by a suitable rechargeable battery (not shown), which can be similar to battery 62, is provided. Computer 301 can receive a data stream from one or more image sensors 302, which can be of any suitable type such as camera 69, geometry sensor 73, camera 68, EOG sensors 71, EEG sensors 72 or a combination thereof. In one embodiment, the sensors 302 include one or more cameras and/or other digital sensors that face outward, that is toward the world or away from the user, and/or inward, that is toward the user. The data feeds from these sensors 302 go to miniaturized computer 301 running an operating system and/or local application(s) and/or networked application(s). In one embodiment, the computer 301 is disposed within the first portion 51 of right temple 47, although the computer could be disposed elsewhere on the frame 32 as discussed above. Right temple 47 can have a removable cover or section 303 for permitting access to the computer 301 and/or other electronic components of the glasses 291.

The glasses 291 can additionally include any suitable left and/or right optical elements or assemblies 306, which can be similar to any of the optical elements or assemblies discussed herein including optical elements 43, 44 of glasses 31, display assembly 80 of headwear 78, optical assembly 113 of headwear 111, optical assembly 153 of headwear 151, optical assembly 192 of headwear 191, optical assembly 232 of headwear 231 or optical assembly 266 of glasses 261. Although only one optical assembly 306 is shown in FIG. 11 , it is appreciated that an optical assembly 306 can be provided for both eyes of the user. The optical assembly 306 can include any suitable the light projector 307, which in one embodiment is a high-speed or frequency three-color laser projector based on a scanning mirror (galvanometer). In one embodiment, the light or laser projector is disposed in one of the arms or temples 46, 47 of the glasses 291 and in one embodiment is shown inside a cavity of the right temple 47 accessible by cover 303. The micro computer system or computer 301 connects to the light projector or laser projector 307. The optical assembly 306 can additional include any suitable optical layers discussed herein, and in one embodiment includes a series of optical strips or layers 311. The strips 311 can be spaced apart across the width of the lens 292, as shown in the right lens 292 in right optical element holder 37 in FIG. 11 , or can be spaced apart across the depth of the lens, that is between the front surface 293 and the rear surface 294 of the lens 292 as shown in the partial view of another embodiment of the lens 292 in the top corner of FIG. 11 .

In one method of operation, computer 301 and its operating system and applications send data to light projector 307. The nature of the projector is that it can send visible photons with software-controlled color and intensity and software-controlled directions. A plurality of light paths 312-314 depicting the paths of respective photons emitted by the projector are illustrated. The arrows in this figure depict how lenses and/or prisms and/or mirrors and/or waveguides and/or other optics can direct the visible photons on paths 312-314 that take the photons from the projector 307 around to the eyewear lens 292, coming in from the side. As the photons then travel across the eyewear lens 292, such travel being depicted as going right to left with respect to the right lens 292 in FIG. 11 , the photons encounter a series of optical strips 311. When a particular photon encounters a particular optical strip 311, it either gets redirected toward the user's eye, or it passes to the next optical strip 311. In one embodiment, the determination of whether a photon is redirected or passed is encoded into the photon's wavelength, position, intensity, polarization, phase, and/or timing. In another embodiment, the determination of whether a photon is redirected or passed is controlled by changing physical properties of the strip 311. In a specific example of this, a strip 311 is controlled through mechanical actuation and/or electromagnetic fields and/or acoustics.

In one example implementation of the optical strips 311, each strip can use Polymer Dispersed Liquid Crystal to be opaque or transparent at a given instant of time, per software command. In a different example implementation of the optical strips, each strip 311 can have a specific wavelength of light that it redirects toward the user, passing all the other wavelengths through to the next strip 311. In a different example implementation of the optical strips 311, each strip can have certain regions of the strip that do cause redirection and other regions that don't, and the projector 307 can use high precision steering of the light to target the photons at the redirecting region of the intended strip 311.

In the embodiment of the lens 292 on the top right of FIG. 11 , strips 311 extend parallel to the front and rear surface 293, 294 of the lens and are spaced apart across the depth of the lens between surfaces 293, 294. The light from laser projector 307 enters the lens 292 from a face or surface of the lens, and is shown as entering the rear surface 294 of the lens. In a manner similar to that discussed above, when a particular photon encounters a particular optical strip 311, it either is retained at such strip so as to be visible by the user's eye, or it passes to the next optical strip 311.

In the embodiment of the lens 292 on the top left of FIG. 11 , strips 311 are disposed in and spaced apart along the width of a first layer 316 of the lens 292, which is secured in a suitable manner to a second layer 317 of the lens 292. In one embodiment, front surface 293 is formed by the second layer 317 and rear surface 294 is formed by the first layer 316. The second layer 317 can be provided with reflective coatings on at least a portion of the surfaces thereof so that the laser lights bounces off such surfaces so as to travel along the layer 317 until the light encounters a strip 311 provided in the first layer 316, and is either redirected towards the eye of the user or continues on to the next strip 311 in the manner discussed above.

Glasses 291 permit the overlaying projected photons onto the real-world scene with high brightness, without blocking the real-world scene from direct view, and without blocking other people from seeing the user's eyes, in a miniaturized form factor worn as a pair of glasses. This system is able to direct light at the user from any point in the eyewear lens, such as lens 292 discussed herein, while occupying only a very small form factor. This system is compatible with the systems and headwear disclosed herein, including the four-dimensional light field display of headwear 111 and 151 described respectively in FIGS. 5 and 6 , and with the system for three dimensional plus dioptric gaze tracking described in FIG. 4 .

In FIG. 12 , a head worn apparatus is shown containing a plurality of components together creating a computer and computer display system (606, 606), which can be used for streaming the real-world view from digital input sensors such as digital camera (604) or a plurality of other digital sensors (610, 600, 604).

Computer system (605) containing computer software or containing a plurality of computer software for displaying data into the computer display for the purpose of enhancing human vision with digital information, including 3-Dimensional graphics, 2-Dimensional graphics, or multiple layers of 3-Dimensional or multi-dimensional data that can be displayed sequentially or spatially, or both sequentially and spatially.

Near-ocular computer display for the purpose of integrating digital information and data into digital images or meta data that can drawn by the display system (606) and seen with the human eyes.

Computer system and software methods for displaying immersive virtual reality, immersive virtual images or immersive videos.

The human wearing the head-wearable apparatus (607) has their inter-ocular distance (601) measured through a plurality of methods such as software system that analyses data obtained from a sensor system or a plurality of sensor systems. For example a digital image sensor system or a plurality of digital image sensor systems, or a digital video sensor system, or a plurality of digital video sensor systems, or a electromagnetic variation measurement sensor system, or a plurality of multiple electromagnetic variation measurement sensor systems, or a plurality of any other sensor system; which then sends data to the computing system which uses software to compute the inter-ocular distance (601).

The human wearing the head-worn apparatus (607) looks through lenses (606) with their eyes, viewing a digital display system (605, 606) or a plurality of display systems (605, 606), containing a single optical element or a combination of a plurality of optical elements, including prisms, mirrors or waveguides and/or other optics that manipulate photons sent from display matrix prior to the photons being seen by the human eye (611).

A head-worn computer device with a display that shows the human eye or both of a humans eyes a digitally displayed version of the real world after the digital representation of the real world has been collected using a digital sensor system or a plurality of digital sensor systems (600, 604, 610) and then processed by the computer system and drawn to the display so that the human can view it (607, 611, 606, 605); in such a case the human may view a direct representational version of the real-world surrounding them, or the computer may display a modified view of the real-world that is containing additional data and information, or the human may view 3-Dimensional or multi-dimensional data that represents a digitally fabricated virtual environment that may or may not exist in the real world.

When the system is in the mode that shows the real physical reality into the human eyes, reality is captured by a miniaturized computer through the sensors (604). There are one or more sensors in item (604). These digital sensors can have different purposes and different properties. In one embodiment, sensors are pointed in different directions (610), sensing different wavelengths of light (or other non-light properties like sonar-ping distance), and having variable angular field of view.

The system transforms images from multiple cameras (600, 604) to generate images that match the perspective of the human eye including situations when the human eye is rotated without having to translate or rotate the visor or camera assembly.

As the miniaturized computer is reading from the sensors (604), it is able to use software (603) to interpolate and/or extrapolate the data captured by the various sensors (600, 604) in order to vary the interocular distance (602, 601) and/or to vary the convergence angle (612).

Varying the interocular distance (602) and convergence angle (612) using the digital image sensor data with the computer system allows the virtual image displayed to the human eye to match the user's real-life inter-ocular distance (601) and convergence angle (612), in order to produce a display system that simulates the appearance of the real world perspective as seen by a human eye, but is displayed to the human from a near-ocular digital display system. Other goals for the system (612, 603, 602, 601) can include variable control of depth perception, or can include widening independent control of the computer software in such a way as to virtually modify visible inter-ocular distance (602, 612, 603) for a number of virtual 3D display purposes.

In FIGS. 19-20 , interface for interactive presentation of data with control via sensed biometric data.

An interface is displayed to a human where data (1901) is displayed and seamlessly integrated into the human eye's perception of the world. An image sensor senses the world from the perspective of a human eye (1902). The sensed data is processed and metadata is extracted (1903) such that additional data can be added to the sensed data in a way that looks accurate to the human visual system. The data is combined with the extracted metadata to create an image stream (1904); that stream is then displayed to the human eye.

One embodiment contains a computation interface with graphical feedback capabilities which includes computer software controllable through biometric feedback (2005, 2006, 2007, 2008).

In one embodiment, the image sensor observes motion of the viewer's hands (2005) and adjusts the process in (1904) to respond to the hand motion, allowing a rendered object to appear as though the human hand was causing it to move. In another example, the position of the human eye is tracked (2006) and used to alter the displayed data (1901), such as causing a rendered object to move up when the human eye moves up.

In another embodiment, electric voltages or currents in the human brain are sensed in such a way that thinking a specific thought triggers changes in the rendered data. When a wearer thinks most thoughts, the brain sensor does not detect the activation thought and the change does not happen (2007). When a wearer thinks a specific thought, the sensor detects the thought and the change happens (2008). Additionally, the sensor may be configured to require a specific thought for a particular duration (2007, 2008).

In FIG. 21 , a system for sharing computer resources with head-wearable computers using dynamically created computer networks is shown.

A head-worn or otherwise wearable computer (2101) communicates over a network and dynamically determines the networking context. In one embodiment this includes networking within a peer to peer proximity-based wireless mesh network (2102) with one or more other mobile or head-worn computers (2104). When a mobile computer receives a signal to execute a procedure, it sends a signal to other mobile computers over the mentioned peer to peer to wireless network protocol. A procedure is executed to determine whether part of the original procedure can be transmitted to a separate mobile computer for execution on that mobile computer (2103).

In one embodiment, a head-worn computer with an image sensor executes a procedure to extract data or metadata from the image sensor's data stream. It signals this to other mobile computers and determines that another mobile computer will execute part of the procedure (2102, 2103). The two mobile computers simultaneously execute separate parts of the procedure. The result of the procedure is made available to both mobile computers (2103).

When a head-wearable computer receives a signal from a previously unseen mobile computer, it signals other mobile computers it is connected with and joins the local network comprised of a plurality of other head-wearable computers or other mobile wearable computers, or any other computer transmitting a compatible network protocol, or any plurality of the aforementioned networking scenarios. The head-worn computers store a representation of the other computers that are reachable.

In one embodiment, a collection of a plurality of head-worn computers (2105, 2108, 2107, 2106) are connected to each other and each stores the path to the other computers. When one computer moves out of range of the links that connect it to others, nearby computers announce the loss of the out of range computer.

In FIG. 22 a ality as a platform is shown, and can include a method for secure recording, transmission, local and remote processing, and display of sensed data from glasses.

A head-worn sensing platform such as glasses (2201) senses data from environmental sensors. The sensed data is transmitted through various mobile communication platforms (2202, 2203, 2204). The data is transmitted to networked computers for processing. The networked computers apply procedures to the received data to extract metadata. The networked computers additionally receive signals from other networked computers requesting access to the extracted metadata. If the requesting computers have permission to access the extracted metadata, the metadata is made accessible to the requesting computers via a software interface (2207). Additionally, the extracted metadata can be transmitted back to the mobile sensing head-worn computer (2203).

The sensing platform also executes procedures on the sensed data using a head-worn computer (2201). Those procedures extract metadata from the sensed data and execute further procedures based on the extracted data. In one example, the head worn computer (2201) transmits data to the mobile computer (2205) that receives heart rate data from a heart rate sensor (2201), and a procedure determines that the heart rate has spiked. This triggers a procedure which turns on an audio sensor and an image sensor. This metadata is additionally transmitted through the previously mentioned mobile communication platforms (2207) to networked computers for additional processing.

The metadata is further processed on the device and are data is generated from the processing. In one example, image sensor data is analyzed to extract information about edges and corners in the sensed data. Additional procedures on the mobile sensing platform request access to the sensed data and the additional metadata. If the procedures are authorized to access the data, the data and metadata are transmitted locally to the additional procedures (2207). The additional procedures perform further processing on the data, and also access networked computers through the mobile sensing platform's network connection. In one example, an application requests a database of images from a networked computer and stores the database on the mobile sensing platform. It then requests access to and applies a procedure to the sensed data and metadata in order to match the sensed data with the saved database of images. The procedures optionally call stored procedures to output data to a display (and/or other outputs) integrated into the mobile sensing platform.

In FIG. 23 , methods for transmission and processing of payment information from a networked digital image sensor are shown, one embodiment contained within a headworn computer system and combined with a digital camera, transmitted across a computer network for the purpose of creating an end-to-end digital transaction processing system, one embodiment of which can be used for virtual currency transactions, real currency transactions or other variable forms of monetary payments, monetary conversions or currency exchange systems.

A form of payment (2302) is placed in the field of view of a digital sensor, for example, a digital camera (2301) such that the camera can observe the form of payment. A networked computer system (2303 a and 2303 b) receives a series of images that represent the form of payment, as taken by the camera. In one embodiment, the camera and head-worn computer could be directly connected, such as an embedded camera (2304 a) inside of eyewear containing a computer (2304) or in another embodiment the system could transmit data in combination with a head-mounted computer and a secondary computer contained inside of another enclosure such as a mobile computer, a desktop computer or a laptop computer (2303 a).

The images are transmitted over a network (2306) to a collection of networked computers for processing. In one embodiment, the images are sent into a networked cloud computer server or servers (2307) for processing. Software executing from the cloud computing server or servers performs analysis on the data sent, and associates account information, payment information and other required data or metadata to secure any form of monetary transaction between one party, two parties, or a plurality of parties. In one embodiment, the payment information can be analyzed from a digital image using a combination of computer vision algorithms or optionally optical character recognition algorithms. The payment information between parties can be extracted and stored as a digital representation of the form of payment to proceed with the transaction. In one example of an embodiment, a credit card, this could consist of the card number, name, expiration date and security code.

The account transaction information is then dispatched via a dispatching server (2308 a). The dispatching server negotiates and authenticates a secure connection with a transaction server (2308 c) and further optionally sends data and details regarding the transaction to a secure computer database server plurality of secure computer database servers (2308 b).

The computer processing the secure transactions (2308 c) executes a procedure to dynamically determine and negotiate with another secure server (2309) based on payment type for the purpose of withdrawing, depositing, and transacting the monetary exchange.

The digital payment processing data that was derived from images captured from or in conjunction with head-worn computer apparatus, using cloud based computer vision, is transmitted to a networked computer (2309) that is authorized to process a payment with the form of payment from the particular banking or monetary exchange entity or entities (2312, 2311) required to complete the monetary transaction. In one embodiment, this could be a third-party payment processor that is authorized to process credit card transactions (2310). In another embodiment, this could be a banking institution such as a FDIC bank. In another embodiment this could be a pre-paid credit authorization and payment system. In another embodiment, this could be a virtual currency transaction system (2310). In another embodiment this could be any third-party transaction system (2310). In another embodiment this could be the Federal Reserve Bank (2311).

In one embodiment, the head-worn computer is networked with other computers and bundles the form of payment and an associated amount to charge together, and then delivers the charge and form of payment over the computer network (2310) to a financial institution (2311, 2312) or a plurality of financial institutions. In one embodiment a computer from a face-worn head-wearable computer delivers a request across a computer network that is analyzed and dispatched to another computer located at different financial institutions (2311) and delivers the charge and form of payment directly between the financial institutions (2311, 2312).

In FIG. 24 , methods for extraction of data and metadata from the world through one or more image sensors is shown.

One or more sensors that collect digital data are used to process and acquire digital data streams, with one or more instance of the sensors running simultaneously either synchronously or asynchronously to collect data and send into a processing, combination and recombination process to transform it into various data formats that comprise and represent features of real world data.

One or more images sensors are used to sense image data for one or more scenes.

The data streams from one or more image sensors are first enhanced by applying a procedure that increases the fidelity of the images. In one example, this could be a procedure that combines sequential images together to produce a more detailed and higher resolution image. In another example, this could be a procedure that modifies the images to reduce the appearance of camera motion between frames, thereby spatially stabilizing the image stream.

The enhanced streams are then processed together using a procedure that merges the information from multiple streams into a single data structure containing both the original sensed data and additional derived data. In one example, the data structure could be an image containing the positions and colors of each point that was sensed in the original scenes, using a procedure that determines the position of points in a scene based on similarities in two images of the same scene.

The combined data structure is then processed by a procedure or collection of procedures that analyzes the data to extract metadata. In one example, a procedure for finding objects in an image is applied to the data structure to determine the position and orientation of one or more objects in the original scenes. In another example, a procedure for detecting patterns such as bar codes is applied and one or more bar codes are extracted from the data structure. This metadata is then stored both with the data structure and in one or more networked computer systems.

The data structures generated by the above procedure are then processed through a procedure that aggregates multiple sequential data structures, extracts additional metadata and generates new data structures representing the aggregated data. In one example, a procedure is applied that combines multiple sequential data structures storing the position and color of points in a scene into a single unified color model of the scene, and additionally determines the position and orientation of the image sensors in that scene. In this example, a procedure is then applied that extracts distinct spatial regions of the model such as the spatial region corresponding to a person standing in front of the image sensor. Additionally in this example, a procedure is applied that extracts distinct spatial and temporal regions together such as the spatial and temporal region (animation) corresponding to a person walking in front of the image sensor.

In FIG. 25 , an interactive interface for viewing, modifying and sharing recorded experiences is shown.

A mobile computer (2502) executes procedures to display an interface exposing a collection of bundles of data (2501) representing sensed observations of the world. The interface is controlled through sensors that transmit signals to (2502). When a control signal comes that indicates that the controller (user) wants to select a bundle of data, the interface changes to display that bundle of data. In one example, the data is video and audio previously recorded by sensors. When selected, a video player is displayed. In another example, the data bundle additionally includes the position of the sensors at the time of recording, and additionally sensed properties of a human controlling the sensor at the time of recording. When selected, the additional position and sensed human properties are displayed along with the video and audio data.

When a control signal comes that indicates that the controller (user) wants to modify a bundle of data, the interface changes to display an editing interface.

The interface additionally exposes a capability to transmit the bundle of data to separate networked computer with a single signal. When a control signal comes that indicates that the controller wants to transmit the bundle to a separate networked computer, a procedure is executed to transmit the bundle in such a way that if the connection between the mobile computer and the external networked computer is broken, the transmission is paused; the transmission is resumed automatically when the connection is restored.

In one embodiment: The optical architecture is based on a principle called “unit focusing” [1] which is how SLR camera lenses work. Unit focusing is the process whereby adjusting the relative z-axis positions of a series of alternating converging and diverging lenses allows one to alter the focus distance and/or the magnification of the image that is passing through the lens system.

As depicted in FIG. 1 , the architecture in this prototype was chosen for its extreme simplicity, and consists of only three lens (including the user's eye's lens), whereas most camera lens systems contain four or five lenses. This simplicity results in predictable lens distortion, but said distortion may be partly compensated for in the software rendering engine, and is also not the most pressing user experience challenge (latency is).

One can quite simply conceptualize the effects of this display by tracing the path that the image of one frame's light takes on its way from the pixel plane (positive Z, at the right side of FIG. 1 ) it originates at towards its final destination of the human retina (negative Z, at the left side of FIG. 2 ):

1. Between the LCD and the “C” lens, the light diverges as it travels leftward.

2. The “C” lens converges the light.

3. Between the “C” lens and the “D” lens, the light converges.

4. The “D” lens diverges the light.

5. Between the “D” lens and the eye's lens, the light diverges.

6. The eye's lens converges the light.

7. The light forms an in-focus image on the retina.

Notice that the total system (including the eye) is symmetrical about the “D” lens. Starting at the “D” lens and moving outward, both sides contain a diverger, then a converger, then a pixel grid. The total system is thus a symbiotic union where half of the components consist of human tissue and muscle, and the other half of manufactured glass and electromagnetic motors.

Eye Tracking: While the user is interacting with this display, each of their eyes are being independently tracking using a pair of cameras. The cameras are modified by removing the filters that block infrared light. This allows the CMOS sensors' red channels to capture infrared in addition to red. Meanwhile, infrared LEDs illuminate the eyes. The reason to capture infrared is that it facilitates the task of pupil tracking: many people have brown irises when viewed in RGB, but in infrared, everybody's eyes irises are very light gray. This creates a clearly defined edge between the pupil and the iris (see FIG. 2 ).

For each eye, three points of interest are tracked in real time using the OpenCV GPU-accelerated computer vision library. Two of the points are the two corners of the eye, and the third point is the center of the pupil.

The eye corners are detected using Oriented Gradient features. The pupil is tracked by taking the xy derivative of the image (edge detection) and then fitting an ellipse onto the elliptical border between the black pupil and the light-gray iris.

Once we know the positions of each of the eye corners and the pupil, these data are used for the following purposes:

The positions of the two corners are averaged to obtain an x,y location for that eye. This allows the rendering engine software to create an effect of head-movement parallax, which is equally important a depth cue as binocular parallax is! [2]

In addition, it is the pupil position data that really lets the display come alive. First, we calculate the 2D displacement between the center of the eyeball versus the center of the pupil. Next, we apply an affine transformation in 3D to convert the 2D gaze displacement into a 3D gaze vector for that eye. Then, normalize the vector.

Once we have the 3D gaze vectors for both eyes, we cast those rays out from the eyeball positions, and find the point in 3D space where the two gaze rays intersect (or come closest to intersecting, by least squares). This gives us the 3D point in space that the user is currently looking at, which is extremely useful! Let us refer to this point as the “vergence point”.

Next, we enhance the precision of our measurement of the vergence point. We achieve this by incorporating an additional source of z-coordinate information. If we cast the x,y components of the vergence point forward directly along the positive z axis, we can follow that line forward until we hit the nearest opaque virtual object in the virtual scene. If we assume that the user is indeed focusing on the object that they are looking directly at, then the z coordinate of said object is a second source of information about the z coordinate of the ground-truth vergence point. Ultimately, we average the two possible z values, weighting each source by 50%.

Once we know the gaze vergence point's z coordinate precisely, we feed this value back into a closed-loop mechatronic control system that actuates the z coordinates of the four movable lenses (two per eye) of the optics system. We also feed the vergence point's z into the rendering engine, in order to software-simulate retinal blur (see chapter 5: rendering).

We control the optical power of the sub-system consisting of the “D” and “C” lenses. We control said optical power quite simply: the optical power measured in diopters is roughly linearly proportional to the distance (in meters) between the “D” and “C” lenses. We always try to keep the midpoint z (in meters) at the “D” and “C” lenses equal to the midpoint z (in meters) of the LCD and the retina; this is just a rule of thumb intended to reduce optical distortion, which I have stumbled upon in my practical experience controlling the system.

So we know that we are able to control the optical power of the “D”-“C” subsystem, now the question is to what goal we want to apply that power. The answer is that we want to counter-act the real-time-changing optical power of the eye's lens, keeping the total optical power of the three-lens system always constant. (The math is easy; the Thin Lens Formula [4] states that the powers of lenses in a system, expressed in 1/meters, combine by linear addition).

By constantly anticipating what z the user will focus on, and counter-acting it in real-time, the mechanical lenses are essentially “dancing” with the biological lens. The human's lens is the lead, and the mechatronic pair is the follow. Every movement that the human's lens makes, the mechatronic system detects and obeys. By perfectly following the moves in real time, the co-focus display is able to ensure that the image from the LCD is always in focus on the retina.

In one embodiment, a real-time, symbiotic intelligent lens system is provided that serves the user by keeping the display in focus, no matter what z distance the user looks to.

At this point, we may choose to add blur to compensate for the blur we've removed (thus enhancing realism). For information about how to add the correctly blurs to each part of the scene automatically, see chapter 5: rendering.

Or we could choose not to add blur at all, allowing every glorious pixel in the user's view to shine with in-focus perfection. (For an example of what this looks like, watch the 2008 live-action+CG movie, Speed Racer.)

Rendering

There are multiple approaches to rendering for a “depth+stereo+parallax” display. Which approach to use depends on whether the objects to be rendered are originating as digital 3D models or instead as 2D and noisy data from camera sensors (e.g. in a pair of glasses with a co-focus on the inside and cameras on the front).

If we are rendering a digital 3D model through a raster pipeline, rendering is as follows:

-   -   render from the vantage points of two virtual cameras instead of         one     -   update the position and orientation of each camera before each         frame, to correspond in real-time to the position and         orientation of each of the user's eyes.     -   in the GL shader:     -   for each polygon, compute the displacement from the user's         vergence z according to the equation:         delta_z(1/meters)=abs(1/(polygon z(meters))−1/(vergence         z(meters))). Note that 1/meter=1 diopter, the unit of reciprocal         distance. If we work in diopters, the equation is much simpler:         delta_z (1/meters)=abs(polygon z (1/meters)−vergence z         (1/meters)).     -   blur (e.g. Gaussian blur) the textured polygon, where the blur         magnitude is directly proportional to the delta_z in 1/meters.

If we are instead rendering mostly-verbatim from a stereo pair of physical 2D cameras:

-   -   the cameras must have a large Depth Of Field, so that they can         capture the entire scene in focus in every frame. They must also         be well-mounted at a fixed and known relative position, with the         ideal displacement corresponding to the average human         interpupilary distance of 63 mm. [3]     -   using Stereo Correspondence, calculate a low-resolution z-buffer         for the image. Express the z's in 1/meters. One common technique         for stereo correspondence is:     -   for each of the left and right images, extra a set of around 100         “keypoint features”, such as SIFT features. SIFT is a trusted         algorithm because it is invariant to affine transforms of the         image, which is great because with a stereo pair of cameras, one         image is more-or-less an affine transform of the other, and the         places where the pixels do not match are caused by ground-truth         z buffer of the actual distances of the objects those pixels         represent.     -   by the affine transform method (homography) described above,         change the perspective of both the left and right camera images         so they look more-or-less like they are both coming from the one         single imaginary camera located halfway between the two, in this         change-of-basis, make sure you remember to transform the         coordinates of the SIFT features as well as the image itself!     -   for each SIFT feature in both images, assign it a partner that         is its nearest neighbor in the *other* image. Heavily penalize         y-distance, e.g. by a factor of 5, because the camera hardware         is aligned and so y displacements of SIFT keypoints must be         spurious. Additionally to compensate bar the spurious keypoints         created by senor noise, do not assign a feature a partner if the         would-be partner is too far away (e.g, more than ˜40 pixels away         in a 1080×720 image)     -   for every feature that has a partner, make that a sample point         in a sparse z-buffer. The z value in 1/meters corresponds         proportionally to 1/(the distance from this SIFT feature to its         partner, in meters).     -   apply the inverses of the affine transforms that we applied to         the camera images, getting us back to the camera's true vantage         points. (Or just retrieve the original images from memory). Also         apply these inverse transforms to the sparse z-buffer, giving us         now the two original camera images as well as a left z-buffer         and a right z-buffer expressed in the basis space of the two         cameras themselves.     -   for each of the left and right images:     -   Gaussian blur every pair of the image in proportion to the         delta_z (1/m)=abs((z-buffer[this x,y] in 1/m−(vergence z in         1/m)). Obtain the missing z-buffer contents by interpolating         along the best-fit surface over the sparse samples.

Calibration

The calibration procedure is extremely simple:

-   1. The user selects how many minutes they are willing to devote to     calibration (the more time, the more hyper-realistic the outcome). -   2. Based on that time window, the software display's the user n many     lit-up “stars” in an otherwise dark view. The software displays the     stars one at a time, requesting the user to look at the star (with     both eyes) and then press a button to confirm. -   3. The stars' positions are randomly located in 3D (randomly so the     user does not get bored by the predictability of seeing the dots in     a sequential row). The more time, the higher the resolution of the     calibration because more samples are taken
